摘要：
In a rotation angle measurement apparatus using a bridge configuration of a magneto-resistance element, a correct angle is not output when a fault occurs. For this reason, there is a problem in which an upper-layer system using the same is broken down. However, in order to solve this problem, there is provided a rotation angle measurement apparatus including a SIN bridge and a COS bridge each of which includes a magneto-resistance element and a detection unit, wherein the detection unit outputs an angle signal based on a signal output from a normal half bridge when a fault occurs in any one of respective half bridges of the COS bridge or the SIN bridge.
